Why don't you go to Macy's first and look around for some nice fitting suits and dress shirts within your budget. Go for the essential suits like navy or charcoal, grey and for the office simply stay away from black suits.

That's the importance of getting the right measurements AND fitting the garment a few times to ensure everything's right. For the tailor to get it right the first fit would be great, but there are times when a couple of fittings are necessary.
